Envisaging the West: Thomas Jefferson and the Roots of Lewis and Clark

Interactive Maps

Using GIS (Geographic Information Services) software, seven maps that shaped Thomas Jefferson's conceptions of the West have been transcribed and entered into databases, making them interactive. These processes link locations referenced in Envisaging the West's documents to corresponding points on the maps. By integrating cartographic information with documentary records, notions of landscape, land use, and geopolitics in Jefferson’s era are illuminated in new ways, demonstrating how these constructs changed over time as westward movement and exploration gradually revealed Western geography, pushing back the boundaries of the unknown from the edge of Virginia to the Pacific Coast. Additionally, high-resolution images and a search function make the information on each map accessible apart from the documents and allow the user to explore the maps with ease. In some instances, where locations could not be conclusively identified or when they fell outside ideas of "the West," points have not been geo-referenced on the maps and are not searchable, but the images are presented in full.
